SEAT CONSTRUCTION.

apl'mcauon mea :my a,

This invention relates generally to seat constructions and refers lmore. particularly to adjustable seats designed for use in bod1es of motor vehicles.

. 6 One of the essential objects of the invention is to provide a seat of this type that is capable of being tilted or adjusted longitud 1- nally with respect to the floor of the vehicle to accommodate persons of different sizes in l rear of the usual steering wheels of such vehicles.

Another object is to provide a seat that may be readily installed and may be easily and uickly adjusted to the desired positionl after l t e installation has been made.

A further object Iis to vprovide a simple j and effective means for detachably holding the seat in any adjusted position.

Still another object is to provide a strong i and durable seat which is sim le in construction and can be manufactu at a compara- 4 tively low cost.'

Figure 4 is a top plan view of one of the split collars. l

Figure 5 is a diagrammatic view of the seat 1n various adjusted positions with re spect to the floor ofthe vehicle body. Figure .6 is an enlarged fragmentary end elevation ofthe seat.

Referring new to the drawing, the numeral 1 designates -a seat that is adapted to be tilted or adjusted longitudinally with respect to the floor 2 of a vehicle body. As

shown, this seat is provided with a flat bottom or, base'B and is supported by suitable brackets 4 and 5 respectively which are connected to the,floor 2, preferably in rear of` the usual steering wheel (not shown) to accommodate the driver o f the vehicle.

In order that the seat 1 may be moved longitudinally ofthe floor 2, the base 3 of the seat is preferablyy provided on its lower 1925. Serial No. 42,416.

face with two longitudinally extending rails 6 having depending longitudinally extending flanges 7 that [are disposed in aligned vertical slots 8 and 9 respectively Iin the upper ends of the brackets 4 and 5. Any suitable means such as the bolts 10 vmay bc used to secure the rails 6 to the base 3 of the seat, while'any suitable means such as the bolts 11 may be employed for connecting the brackets 4 and 5 respectively to the depending flanges 7 of therails. As shown, these bolts 11 extend transversely of the brackets 4 and 5 respectively, through elongated slots 12 and 13 respectively in the iianges 7 and are held in adjusted position by means of suitable nuts 14. Thus, withthis construction, when the nuts 14 are loosened the seat l maybe readily adjusted forwardly or rearwardly on the bolts 11 to the desired osition andfmay then be held in such position by tightening the nuts.14.

To prevent the seat 1 moving accidentally, for instance if the nuts 14v should work loose while the seat is in use, the upper edges of the rear slots 13` are preferably scalloped to provide a series of arcuateshaped recesses 15 for receiving the rear bolts 11. Thus', the combined weight of the driver andrse'at, or inA fact the weight of' the seat alone will suffice to hold the rear bolts 11 in.- enga e-f ment with the proper recesses 15 to there y prevent any accidental longitudinal movel mentof the seat.

In lorder that the seat may be tilted, the

v forward brackets 4 have relativelyi'lat bases .16 that are secured,

preferably by screws 17 to the floor 2, whi. e the rear brackets 5 preferably have cylindrical Shanks 18 that are movable-vertically in suitableopenings 19 in the loor'2 of the vehicle body.' Thus, the seat 1 isad'apted to swing on the forward bolts ll/which constitute suitable fulcrums therefor; For holding the seat 1 in adjusted position, I preferably provide suitable split collars 20 that are secured tothe floor 2 and are adapted to be clamped upon the cylindrical shanks 18 of the brackets 5. Any suitable means such as the bolts 21 ex tending transversely of the split collars 20 may be employed "for effecting the clam ing action, while suitable nuts 22 may e threaded on the bolts 21 to retain the same in adjustedpposition. Thus, with this construction, the seat may be adjusted to an inclined position by merely raising or lowering the s anks 18 in the openings 19. Inasmuch as the forward bolts 1l constitute fulcrums for the seat during such tilting movements, the movement of the forward end of the seat will not be very noticeable. However the movement ot the rear end of the seat will be suticient to raise or lower the occupant of the seat to the desired position. For instance, a short person would ordinarily desire the seat elevated so that a better vision could he obtained, whileon the other hand a tall person would be satisfied with the seat in lowered position.

It desired, the seat l may be provided beneath the base 3 with suitable compartuients i'or receiving tools, accessories and the like. As' shown, this compartment comprises a flanged receptacle tray 23 that iuay he Secured by any suitabley means to the lower face of the seat base 3,

From the foregoing description it will be apparent that the seat l may be readily tilted or adjusted longitudinally of the floor 2 to accouuuodate persons of di'l'erent sizes. Although the seat is primarily designed as a drivers seat, it is apparent the saine may be readily used in other places whenever found desirable. y

lVhile it is believed that from the foregoing description, the nature and advenitages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within`the scope of what is claimed.

What I claim as my invention is:

The combination with a support having a seat to be adjusted longitudinally of the support., the, lower end ot one of said brackets being permanently secured to said support while the lower end of 'the other bracket is engaged in said opening for ad-I justing the seat to a plurality of vertical positions, the fastening element at the upper end of the bracket which is permanently secured to the support forming a ulcrum for said seat during vertical adjustment thereof.'

ln testimony whereof I aliix my signature.
